The distribution characteristics in sea water and the accumulation in benthic organism of 666 ( bhc) in the nearshore of East Guangdong Province

粤东海区水体中六六六的分布特征及其在底栖生物体内的蓄积

Subindex of ecological vulnerability included species importance, plankton diversity and benthic organism diversity, and region importance.

生态脆弱性指数的子指标包括物种重要性、浮游和底栖生物多样性、区域重要性。

Compare to the historical data, the species of benthic organism reduced significantly. And the number of stain resistance species increased.

与历史数据相比，底栖生物的种类数明显减少，而耐污性种类的数目相对增加。

Sediment quality in waters not only affect the benthic organism, but also has close relation with the water quality due to the frequent pollutant interchanges between the sediment and overlaying water. The polluted sediment often becomes the potential source to pollute waters.

水体沉积泥沙质量不仅对底栖生物具有影响，而且由于泥沙与上覆水体相互间频繁的交换作用，泥沙质量与水体水质也有着密切的关系，污染的泥沙往往会成为水域的潜在污染源。
